The SD association has dubbed this brand of gadgetry the SDXC
Where SD stands for something, XC stands for Extended Capacity. Engineers are not the creative types. The product is dreamed to have a 2TB capacity and write/read speeds of 104 MB/second. Two terabytes is a lot of crap.

It means

100 hi definition movies

60 hours of HD recording

17 000 images

Keep in mind that this is merely a drawup, a spec, and not the real product. Development/production could begin as early as next year, but again, 2TB is an awful lot to mash into an SD card, which makes me wonder if the image above is drawn to scale.
